August 2020 | New paper on the end-Permian mass extinction

The Permian-Triassic boundary is outcropping in the stream bed of Deltadalen, Svalbard. A 100-meter-long core was drilled one kilometer south of the outcrop in 2014, recovering the boundary interval. The Grusryggen mountain in the background. View to the south. (Photo: Julian Janocha.

Mass extinctions – Lessons from the past

A new study led by Dr. Martin Schobben (Museum für Naturkunde, Berlin), with co-authors from the Dept. for Geosciences (UiO), describes the causal chains between environmental changes and mass extinction at the Permian-Triassic boundary about 252 million years ago. From this study, scientists can get a glimpse of what might happen to biodiversity under the predicted global warming in the near future. New publication in Nature Geoscience.

This new study analysed two geological sections in Svalbard: one at Festningen in western Spitsbergen, and a core that Sverre Planke and his team (University of Oslo/Natural History Museum in London) recovered from Deltadalen in central Spitsbergen
